Z1 Motorsports: VQ37 Intake Plenum Power Mod 370Z & G37
 

Nice! Can I install this and run it without getting a tune? Will it be safe?

On the dyno, is that the only mod that Z has?

Z1 told me you absolutely need a tune with this

What gains will this produce on a forced induction Z? My Z is on spray and I was going to pick up an m370

I spoke to John and he said the tune is highly recommended. But obviously getting a tune gives you the best power output.

Damn it lol but thanks :tup: I wanted to get this as my first mod but I might have to wait since I don't want to tune it with just one mod on the car :shakes head:

What exactly is modified inside the manifold?

This is on my short term mod list, along with headers!

Is there a group buy possible for this?

Stuff and things… Cant wait to pick it up tomorrow!! (depending if my short tails come in)

How much hp will this mod ALONE make?

Is that after a tune? I'm looking into this intake manifold for my next mod...what's the warranty on it? Will I get those power gains if I order the Osiris standard and comes w/ the maps alreay programmed into the tune? Or do I need a custom tune?

with all the mods i have currently is this even worth adding? also i'm guessing i would have to get a new tune after adding this?

To answer the last two posts.

I'd like to know the same. I plan on having my car dyno'd later this year, but would like to go ahead and order the manifold + exhaust mods now.

To reword the question... Can the car be run safely without having it tuned with the intake manifold? I dont mind if im not making the most HP, but then again I dont want my car running lean and damaging the motor.

Yes. I have every bolt on mod without a tune. Car runs fine, not lean, the ECU took care of it

Wow, you must never go full throttle ;)

50 times a day, and last I checked I haven't blown a motor

Any new word on this? Any dyno independent dyno runs?

Is this using a oem VHR manifold or the 350z HR manifold?

oem

curious about this....i have the motordyne manifold...wondering how this compares

Interested, but I would like to know what is modified inside or is it only ported and polished?

Also, I'm looking to do your Z1 Sport brake upgrade package in the summer (with the 2-piece front rotors and some other upgrades) and was wondering if you had any forum pricing and/or teacher discounts and/or cheap batich discounts? :tup:


Thanks in advance.

I dont think they are going to indulge what exactly they did to make the extra power...

I want to purchase this manifold and get some independent dyno numbers. Would Z1 be willing to help pay for dyno time? I can show base run w/ stock manifold(current tune), Z1 manifold run (current tune), and Z1 manifold w/ re-tune from a reputable shop in NH. Granite State Dyno DynoJet 224x.

Obviously, I don't expect them to cover all the costs, but if they want to PM me, we can get some independent dyno numbers and discuss this further. If not, I'm probably just going to purchase and install the manifold myself and hit the dyno for a re-tune. It won't give us the whole picture, but we'll get an idea. I'm looking to do this by Friday of this week.

I dyno-ed there 304/248 w/ FI exh. Stillen g3 and ART pipes SAE corrected.

that dyno is pretty hard to make out. Can we get one with an averaged run between the 2 so it's easier to compare? The only thing clear form this dyno is that there's more peak. I can't make out which line is which for the rest of the curve.

would this mod require new gaskets?? i am about to click the "checkout" button. :)

I reused the gaskets from my stock manifold and throttle bodies. The gaskets are rubber and mine were not crushed or deformed in any way. Also, I remember reading somewhere that new gaskets are unnecessary.

Let us know how it works out. I've been waiting for more data.

I am going to Z1 on the 19th. I will get a before and after dyno with the Z1 Upper plenum. I will keep yall up to date. :tiphat:

How much they charge you with the dyno tune?

Ive already tuned there before so im not sure. ill let you know as soon as I find out.

Thanks would like to know also if there is much significant improvement in performance worth the time and investment.

What I'm really looking for is an increase in torque.

Last time I tuned there. I was 312/258 with G3 intakes and Injen exhaust. Now I have test pipes and under-drive pulleys, will get tuned with these mods and then have Z1 install the plenum and re-tune again immediately.. I have a 25 row oil cooler on so I should get consistent pulls since this will all be on the same day. I too am looking mostly for torque gains.

Got the car re-tuned over the weekend. I did a before run which was 295/245. After the Z1 plenum I was at 305/254 this was within an hour of each other. It was a rainy damp day so that might be why I was at less power than my previous run a few months back. I will have the dyno sheet up as soon as I get it from John. I will be going back again very soon for another re-tune due to unforeseen circumstances.

In all I can say that I feel a lot more power in the mid range and all around. I will give a more detailed review as soon as I get the car tuned one more time.
